This 'heart glyph' tank is made of 100% cotton.
The reason why it is named 'heart glyph' is because the drawing came through after I had a unique experience of beings that came to work on my heart. They came through as tiny mechanics, operating on me in mysterious ways. Maybe some of their medicine gets to translate itself through this piece as you wear it close to your chest ;)
As you can see in the photos the front and back print vary, yet are based on the same drawing.
